Embodiment 1

[0066] Such as figure 2 As shown, first scan the image inside the brain region 1 through the CT instrument, and then determine the three-dimensional space coordinates of the target point 101 (lesion), place the coil on the top of the brain, and obtain the three-dimensional space coordinates of the coil and the whole brain through the visual scanning sensor 302 information, extract the coordinates of the center point of the coil; then transmit the three-dimensional space coordinate information of the target point 101 and the center of the coil to the positioning device 4, and obtain the spatial angle of the coil through the calculation unit 401 in the positioning device 4, and the mechanical arm 403 according to the spatial angle The data rotates the coil to the designed position such that the magnetic field orientation of the coil acts on the target point 101 . Repeat the above steps to place multiple coils. The superposition of the magnetic field vectors of multiple coils no...

Embodiment 2

[0068] Such as image 3 As shown, the computing unit 401 is connected to the robotic arm 403 and the visual monitoring sensor 302 , the robotic arm 401 is connected to the visual monitoring sensor 302 , and the visual monitoring sensor 302 is connected to the PC terminal 404 . The scanning device 3 transmits the data to the computing unit 401 in the positioning device 4 through modules. The robotic arm in the positioning device clamps the coil in the stimulation device. According to the implementation steps of the technical solution, firstly, the three-dimensional space coordinates of the target point 101 (lesion) are determined by scanning images with a CT apparatus. According to the location of the lesion, a position closer to the lesion is initially selected as the center point of the coil, and the coil is manually placed there and then clamped by the mechanical arm in the positioning device 4 . First, scan the image inside the brain region 1 through a CT instrument, and ...

Abstract

The invention provides a system and a method for transcranial magnetic stimulation directionally superposing a target brain area. The system comprises a stimulation device that can be arranged on a surface layer of a brain area, a scanning device capable of scanning the brain area and the stimulation device, and a positioning device capable of positioning the stimulation device. The scanning device is connected with the positioning device. Using the system and a method for transcranial magnetic stimulation directionally superposing a target brain area, a magnetic field can be directionally stimulated to any area in a brain and stimulation to non-target brain areas is weakened. The system and the method solve problems in the prior art that a target area of magnetic field action is limited,and the magnetic field is difficult to flexibly stimulate different areas of the brain. The system and the method are applicable in the field of transcranial magnetic stimulation, and is also suitableto be used in directional magnetic stimulation of any position in other fields.

Description

technical field [0001] The invention belongs to the field of biomedical engineering, and in particular relates to a transcranial magnetic stimulation system and method for directional and superimposed target brain regions. Background technique [0002] Transcranial magnetic stimulation technology is an important technology in the field of biomedical engineering. It can penetrate the skull through high-field-strength pulsed electromagnetic fields and act on nerve tissues in deeper positions without penetrating the skin to install devices. It is non-invasive and painless. Etc. Its mechanism of action is that the changing current in the coil produces a changing magnetic field, and the changing magnetic field acts on the brain to cause an induced electromotive force, thereby inducing the excitation or inhibition of cells. [0003] However, one of the reasons hindering the clinical development of this technology is that it is difficult to achieve directional stimulation of the t...
